19.8k 0.1% resitor is not available for production

[filcarv]

The 19.8k resistor is not available on the market, which is significantly delaying device production.
The PCB has already been produced, which means we are restricted to the 0402 case.

With 0.1%, we can find 19.6k and 20k. Can any of these be used? If not, please provide an MPN.

You may replace these resistors with

200R -> 301R (0.1% or lower)
19.8k -> 29.8k(0.1% or lower)

this is preferred. If this does not work then,

200R ->198R (0.1% or lower)
19.8k -> 19.6k (0.1% or lower)

is also acceptable. Why do we need these tight tolerances? Because the dividing ratio is small (0.01), the divider tolerance will always be approximately double the individual resistor tolerance. We want channel to channel variability and absolute DC accuracy to be significantly better than 2 parts per 100 (2%) which is what we would get with 1% resistors.
